#"see explanation"#

Explanation:

#"one way is to find the intercepts, that is where the graph"#
#"crosses the x and y axes"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#

#x=0rArry=15larrcolor(red)"y-intercept"#

#y=0rArr15x+15=0rArrx=-1larrcolor(red)"x-intercept"#

#"Plot the points "(0,15)" and "(-1,0)#

#"Draw a straight line through them for graph"#
graph{(y-15x-15)((x-0)^2+(y-15)^2-0.04)((x+1)^2+(y-0)^2-0.04)=0 [-40, 40, -20, 20]}
